Summary

  o A vulnerability in the web-based management interface of Cisco Crosswork
    Change Automation could allow an unauthenticated, remote attacker to
    conduct a cross-site scripting (XSS) attack against a user of the web-based
    management interface of an affected system.

    The vulnerability is due to insufficient validation of user-supplied input
    by the web-based management interface of an affected system. An attacker
    could exploit this vulnerability by persuading a user to click a crafted
    link. A successful exploit could allow the attacker to execute arbitrary
    script code in the context of the affected interface or access sensitive,
    browser-based information.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.
